摘要:
Techniques to manage a whiteboard for multimedia conference events are described. An apparatus may comprise a whiteboard manager component operative to manage whiteboard recording, image processing and reproduction operations for a multimedia conference event. The whiteboard manager component may comprise an image quantizer module operative to receive an image of a writing surface with pen strokes, and quantize each pixel of the image into a predetermined number of colors, an attribute extractor module communicatively coupled to the image quantizer module, the image quantizer module operative to extract stroke attribute information for the pen strokes from the quantized pixels, and a whiteboard interface module communicatively coupled to the attribute extractor module, the whiteboard interface module operative to send the stroke attribute information to a meeting console for rendering as digital pen strokes on a digital writing surface. Other embodiments are described and claimed.
